Please uninstall these drivers or ensure the mesa libGL libraries precede nvidia's via LD_PRELOAD. You can detect if nVidia's libGL precedes mesa's by(poky-qemu also does this) user@machine$ ldd qemu-binary | grep -i nvidia If find something like libGL.so.1 => /usr/lib/nvidia-current/libGL.so.1 libnvidia-tls.so.260.19.06... Qemu is linked with nVidia's libGL, and likely to get segfault:( There are workarounds for different host system. On ubuntu, you can prepend following environment variable before qemu starting command to fall back to mesa's libGL LD_PRELOAD="/usr/lib/libGL.so $LD_PRELOAD" qemu ..... 12864 1 richard.purdie 2011-03-21 07:12:14 +0000 The scripts themselves now warn about this problem. 12945 2 edwin.zhai 2011-03-23 19:04:19 +0000 Verified!
